Vim syntax conceal in context

阅读更多关于 Vim syntax conceal in context

问题 I want to conceal variables with names based on Greek symbols and turn them into their Unicode equivalent symbol, similarly to how vim-cute-python works. So for instance, I have this syntax match scalaNiceKeyword "alpha" conceal cchar=α defined in a file for concealing within Scala files which works great except that it's overly aggressive. If I write alphabet it then gets concealed to become αbet , which is noticeably wrong. How can I modify/expand this conceal statement so that it only

Unable to count the number of matches in Vim

阅读更多关于 Unable to count the number of matches in Vim

问题 How can you count the number of matches in Vim? For instance, for the text <? 回答1: :%s/<?//ng See :h count-items . 回答2: Count-items describes what you are after. :%s/<?/whatever/ng This is the substitution command, but the n flag avoids the actual substitution. 回答3: :help count-items In VIM 6.3, here's how you'd do it: :set report=0 :%s/<?/&/g # returns the count without substitution In VIM 7.2, here's how you'd do it: :%s/<?/&/gn # returns the count without substitution 来源： https:/

阅读更多关于 vim's tab length is different for .py files

问题 In my ~/.vimrc I set tab to me 2 spaces long set shiftwidth=2 set tabstop=2 However when I open a .py file, tabs are 4 spaces long. I don't have specific configuration for python files. ~/.vim/after is empty and searching for py doesn't raise any suspect lines. Have you ever experienced that? How to solve such a behaviour? 回答1: It’s defined in the general Python filetype plugin file ( $VIMRUNTIME/ftplugin/python.vim ): " As suggested by PEP8. setlocal expandtab shiftwidth=4 softtabstop=4

阅读更多关于 How to select SuperTab completion suggestion without creating new line?

问题 When I hit Enter on SuperTab's popup suggestion, it automatically creates a new line at the end of the inserted keyword. Is it possible to select an option in the SuperTab popup without creating a new line? More specifically, is there a way for me to configure space as the method of selecting the code completion suggestion? 回答1: inoremap <expr> <Space> pumvisible() ? "\<C-y>" : " " Note the <C-y> that accepts currently selected option, you may want to use it directly instead of remapping

vim - call function inside 'replace' expression

阅读更多关于 vim - call function inside 'replace' expression

问题 I understand you can call a function in a vim search/replace operation. For example: %s/regex/\=localtime()/g will replace anything matching 'regex' with the current epoch time. The problem is, I can't add anything else to the 'replace' expression. For example: %s/regex/epoch: \=localtime()/g does not treat 'localtime' as a function anymore. Rather it just prints 'epoch: =localtime()' as a string in the replacement text. The intention is for it to print 'epoch: 1353085984' instead. Is there

vim system register * and + not working

阅读更多关于 vim system register * and + not working

问题 :echo has('clipboard') returns 1, but whenever I execute "+yy" or "*yy" nothing seems to be in those registers. If I use regular yy to copy another line of text, then try to paste from the register using CONTROL+V nothing happens. If I try "+p vim pastes the line of text I copied using the regular yy command. What's going on here? I'm on FreeBSD by the way. 回答1: Your vim version may not be compiled with X11 clipboard integration. In vim run the :version command and look for xterm_clipboard in

alt+backspace to delete words in vim

问题 How can I remap alt+backspace to delete words like native *NIX text manipulation? I checked out this thread: Using alt+backspace key in vim command line to delete by words And the examples like: cmap <a-bs> <c-w> and :imap <A-BS> <C-W> don't do anything. And the accepted answer was actually to not even remap it, but to use ctrl+w . Since VIM's alt+backspace doesn't do anything I'd rather remap it to something I'm used to. I'm using terminal based VIM (specifically in iTerm) 回答1: The Alt/Meta
